I am having an issue with a postfix mail server and would appreciate
any advice on how to trouble shoot it. I am at this point completely
lost. The problem we are having is that when a user tries to send a
message they have a good chance of getting one of the following errors
from their client

1. the connection to the server was interrupted
2. the connection to the server timed out

this happens most of the time on the first try to send the message and
in my testing a message will at some point go whether it is on the
1st, 2nd, or even 3rd try.

This is an inherited system and I nor anyone else currently employed
knows much about it so what I am hoping is that someone on this list
could help get started trouble shooting my system. I realize I have
not given much info about the system but I am not really sure what is
pertinent.

Thanks

... Have you looked at the Postfix logs? http://www.postfix.org/DEBUG_README.html#logging If that produces no output, search the logfile for records with the

... guess of the day: their anti-virus/firewall blocks them or is too slow (sometimes people pause Kaspersky and don t realize that they need to reconnect

(sometimes people "pause" Kaspersky and don't realize that they need to
reconnect after that)

postfix logs all connections. if you don't see the log, then either you
have a broken syslog (and you need to fix it first) or the connection
never made it to postfix. in either case, it's not a postfix issue.

see the DEBUG README for infos on how to debug the issue, and how to
report problems or ask for help on this list.
